To all whom t may concern.'

Be it known that I, MICHAEL SLOKAR, a subject of the Austro-Hungarian Emperor, and residing at Zara, Austria-Hungary, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

The Subject-,matter of my invention is a rail joint, in which slice bars and bolts for connecting the rail ends one to another and the latter to the ties are not employed.

My invention substantially consists in the combination of a member, hereinafter called the core, inserted between the rail ends with a serrated tie-plate which connects therail ends and consequently is a substitute for the splice bar, special attachment devices being provided for connecting the rail joint with the tie. l

One illustrative embodiment of my invention is represented by way of example in the accompanying drawings, wherein:-

Figure 1 is an end. elevation, partly in section on. the bent line I-I in Fig. 9;l

Fig. 2 is a like view, partly in section on the bent line VH-VH in Fig. 9; Fig. 3 is a side elevation, showing the outside of the rail, partly in section on the line VIIIM VH1 in Fig. 9, and Fig. 4 is a side elevation showing the outside of 'the core; Fig. 5 is a section on the line IV-IV in Fig. 1, Fig. 6 a section on the line V-V-in F1 1 and Fig. 7 a section on the line VL-VF in Fig. 1; Fig. 8 is a side elevation of the rail joint, partly in longitudinal section, Fig. y9 a lan view of the same partly in horizonta section, and Fig. l() is a Vplan view of theiron tie-plate for wooden ties; Fig. 11 is a lan, and section, showing a joint plate and ig. 12 a like view showing the intermediate plate, while Fig. 13 comprises two sectional elevations taken at right angles to one another showing the forked end of the clamping rod forming the only assembling tool, and Fig. 14 is an isometric projection illustrating the insertion of the core with the twin bolt at .the inner side of the rail.

Referring to the drawings, my improved rail'ljoint comprises a core 1 which is inserted from above between the suitably cut ends 2 of the rail head and held down by the threadless twin bolt 3. For this purpose, the webs 4 and the rail bases 5 are cut i fectly centrally, a space 6 being provided for expansion. In the rail heads 2, on the contrary,.the ends of the rails are cut away the length of the corel and each end is cut off at an obtuse angle at the inside at 8 and at right angles at 9, as clearly shown in Fig. 9.

1n the web4 l provide lugs 10 and a recess corresponding thereto at 11 in the core 1. This core is cut to lit the ends of they rail heads, there being provided between these j the cheek 13 on the inside is strengthened at bothy ends by the projecting shoulders or abutments 14 whichvrest on the top face of the base 5 of the rail. In consequence of the slanting joints in the rail head 2 the cheek 13 of the core 1 is Supported vertically at the art 15 and is longer than the cheek 12. T e latter is only suliciently long to provide holes in the same for the twin bolt 3. The cheek 12 is provided in addition with a recess 16 for receiving the stay 17. This latter is an iron plate reinforced with ribs 18, 19, 20, 21 at its edges, resting at 22 on the base 5 of the rail, and possessing shoulders or abutments 23 which enter into the recesses 24 in the tie-plates 25 or 26 and embrace the base 5 of the rail, 1t lends the raila greater pressure basis, and the rail is thereby prevented from tilting over even when the base clamp is not perfectly tensioned.

The tie-plates 25, 26 are necessitated tol provide the slanting position of the rails and are wedge-shaped in section, as shown vin Figs. 11 and 12. They are provided at each side with two upwardly projecting ribs 27 which embrace the base 5. Further, inwardl projecting teeth 28 are provided on the p ates 25 which engage in corres onding notches 29 in the base 5 of the rai 'and allow the rails to shift longitudinally only an amount occasioned by expansion, while they )revent the rails creeping and also contribute in maintaining the central position of the rail ends on the common tie.

The tie-plates rest o-n the ties 7. These are connected with the rails on the one hand by the stays 17', each of which has a shoulder or lug 30 shaped like a nail head at 21 and a .Lshaped lug 31 at 23 engaging in an oblong hole 32 in the tie 7. In order e to insert the lug 31 into this hole, the latter is enlarged at 33. If the tie 7 is shifted longitudlnally. into the position shown vin the ballast, whereby increased capability of carrying lizing t is obtained in consequence of utie breadth of the ties better'and the ballast can'be tamped along the limbs 35. The .twin bolt" 3 requires no attachment because afterthe base of the rail has been clamped, the center of the common head plate 38 is in front of the head 36 of the clampA 37 and is thereby perfectly prevented from sliding out.

The head plate 38 of the twin bolt is located on the inner side of the rail. The clamp. 37 for the base of the rail is located here also; this clamp serves, on the one hand, for holding down the base 5 of the rai-l. and, on .the other hand, for securing the bolt 3 and' for eabling'the rails to be displaced -relatively tol the stayl? of the rail head, whereby' theuattachment of the rail with the tie becomes stable and cannot work loose.

The clamp comprises the clamp head 39.

and the projections 40 and 41, the former being employable at the inner and the latter at the outer side of the rail; also, the foot 42 engaging under the clamp head, the toothed racks 43 and 44 extended backward, the hooks 45 and the toothed racks 46 and 47; a casing.50 incloses all these parts'.

The function of displacing and'adjusting the clamp 37 is performed by the three racks 43 and 44,' 44, whose teeth diverge of the length of a tooth from one another, so that -when the clamp is shifted always onev of the three racks remains operative, whereby the number of teeth can be kept large and nevertheless it is possible to adjust the clamp by small amounts. The central, larger rack 43 is firmly welded to the clamp head 39, while the two otherracks 44 are arranged pivoted on both sides of the same on a rivet or bolt 48. The center rack 43 has its rear 4end enlarged u ward, thereby forming a rivet or bolt 49 or the attachment of the casing 50. With the central rack 43 there corres ondsv the counter rack 46 which is welde to the hook 45,

- on which the counter racks 47 located on The racks are guided by two small frames 52 and 53, the former being attached to the hook 45 and the latter by rivets at 53 to @e two upper lateral racks 44. Springs 54 and 55 are arranged at the above mentioned frames for causing the racks to engage more ,c ertainly. A rod'.56, shaped specially according to Fi 13, having projections 57 Ais used for shi ing the clamp 37 relatively to the baseof the rail. After the clamp has been inserted .into thev groove in the.- tie it can`be 4displaced byplacing the rod 56 on it in such manner that the projections 57 lembrace both sides of the clamp 37 at the bow 58 secured to the hook 45, as is repre-.

sented at the right-hand of Fig. 2 in which the rod 56 is shownl in dotted lines. In order to enable the lever or rod 56 to operate when the clamp 37 'is displaced according in each instance to the extension of the same, shoulders 59 and 60 are provided on the back of the rod and hook-shaped plates 61 are riveted to the two sides of the'clamp.

In the event of removin the rails and for pushing together the hoo s 42 and 45 for the purpose of adjusting the clamp 37 for altering the gage, the three racks 43 and 44 must be released simultaneously by means of the lever 56. To this end, for lifting the racks 44 a shoulder 64 is provided on the frame 55 at each side of the casing, and for lifting the central rack 43 the bow 59 provided at both sides with shoulders 65 1s attached to the back of the casing, so that all four shoulders 65 and 64 can be seized simultaneously by the rod 56. The rod is placed on the plate 51 and used as a -lever to release the upper racks 43 and 44, 'whereby it is possible to shift the clamp head 39 together with the hook 42 in the opposite direction to the teeth with the aid of a second lever, as is indicated by dotted lines at the left of Fig. 2. For dismantling the clamp recesses 36 suitable for receiving the point 57 of the lever are provided also in the top part at both sides of the clamp head. The hooks 42 and 45 engage in the grooves 62, 63 in the tie 7 in like manner I as the lugs 30, 31.
